Is there an application in windows wherein you can see available shortcuts so that you can actually see if you are repeating a keyboard shortcut or not.
Often times I tend to assign similar shortcuts to applications.
To some degree, yes. I even wrote one years ago specifically for this purpose.
• Keyboard shortcuts that calls applications
• Built-in Windows shortcuts
Those are the same. By default, Windows Explorer has several hotkeys (mostly using the ⊞ Win key) that perform various actions. These can be disabled with the
NoWinKeys registry entry. In addition, Explorer is responsible for the hotkey you set in the properties of a Windows shortcut.
Keyboard shortcuts in applications
It is possible for a program to detect what hotkeys are in use, and it is even possible (using hooks) to find out what programs have allocated which hotkeys. However, there is no way to know what function a hotkey performs. Moreover, when the program that binds a hotkey is not running, then there is no way to detect the use of the hotkey at all.
The only way that a program can provide details like what function a hotkey performs is for the developer to research each program individually to find out what hotkeys it uses and enter them all manually. Worse, many programs allow the user to change, add, and delete hotkeys, which would make it impossible for a program to provide this information.
Is there an application in windows wherein you can … manage the available shortcuts
No, there are no programs that can modify hotkeys in other programs. There might be a (very) small handful of programs that can change the hotkeys of a specific program (among other tasks related to that program), assuming of course that the program’s hotkeys are stored in a manner that is accessible by external programs, but there are certainly no general-purpose programs that can modify hotkeys for any given application.
If all you need is to see a list of taken hotkeys, then there are several options, but if you want to see which programs they are used by, then the only program I have seen which can do it (my own included) is the free Windows Hotkey Explorer.
